Thanks for the articles - I've been reading everything I can find since I've been fighting ich in my 90 gal and following some very good advice.

One thing - most advice I've been given when using heat is that 85F is adequate to kill ich. These two articles quoted here, however, say 86F.
I'm 6 days in to heat treatment at 85F. Should I increase the temp one more degree for the remaining 4 days?
Or do I need to start counting all over and do 10 days at 86F?
Or just stay the course at 85?
The last thing I want to do is end up with another outbreak because I was 1 degree too low during the heat treatment. But I also don't want to put more stress on these fish

thanks so much
